The chip firing game is a simple example of a confluent system, which is a central notion in algebraic combinatorics and particle physics. That is, given an initial distribution of chips on a graph, there are many ways to "play" the chip firing game, but they all lead to the same result. Jim Propp introduced a variation on chip firing on the infinite line graph in which the chips are labeled.... More >

A central issue in studying uniform behaviors of Riemannian manifolds is to obtain uniform local \(L^{\infty }\)-bounds of the curvature tensor. For manifolds whose Riemannian metric satisfying certain elliptic equations, e.g. Einstein manifolds and Ricci solitons, local curvature bound are expected when the local energy is sufficiently small. Such estimates, referred to as \(\epsilon... More >

Newly arrived J-1 postdocs, professors, researchers,short-term scholars, and visiting student researchers are required to attend this meeting to validate their arrival in the U.S. Information on immigration regulations, travel, employment, resources for families, health insurance and other practical information will be discussed.

Deninger and Werner developed an analogue for p-adic curves of the classical correspondence of Narasimhan and Seshadri between stable bundles of degree zero and unitary representations of the topological fundamental group for a complex smooth proper curve. Using parallel transport, they associated functorially to every vector bundle on a p-adic curve whose reduction is strongly semi-stable of... More >

Robust optimization (RO) has emerged as one of the leading paradigms to efficiently model parameter uncertainty. The recent connections between RO and problems in statistics and machine learning domains demand for solving RO problems in ever more larger scale. However, the traditional approaches for solving RO formulations based on building and solving robust counterparts or the iterative... More >

If you need to write a grant proposal, this workshop is for you! You'll get a headstart on defining your research question, developing a lit review and project plan, presenting your qualifications, and creating a realistic budget.

The workshop is open to all UC Berkeley students (undergraduate, graduate, and visiting scholars) regardless of academic discipline. It will be especially useful for... More >

Persistent homology allows us to explore the topology of data. We will see examples of computations of persistent homology of affine and projective varieties. We will also discuss my ongoing research with Emil Horobet to prove the algebraicity of persistent homology.

Coupled oscillator networks can be used to implement general-purpose Ising machines. Such Ising implementations are much more scalable and much easier to design and fabricate than alternatives that have been proposed.

This talk, based on Victor Zatsepines recently published book, Beyond the Amur: Frontier Encounters between China and Russia, 1850-1930 (UBC Press, 2017), illuminates the varied social, economic and political contacts that enlivened the borders of the two empires (Qing China and Romanov Russia) and their successor states. The author argues that the Amur frontier region functioned as a meeting... More >

Speak Swahili with your fellow Swahili students and enthusiasts over a drink at Blue Door Cafe (check for location updates). Each person will support their own beverage purchases, but we will provide the good company! And of course, Swahili speaking only! All skill and experience levels are welcome. Karibuni sana!

What does music tell us about the sustainability and precarity of publics? How can we use music rehearsed, recorded, archived-- to engage histories of erasure and displacement while imagining new forms of community and collaboration? My talk will explore these ideas through my project Hit Parade: Live in San Francisco (for the SFMOMA/SFPL Public Knowledge series) which combines archival... More >

In-Between Places (사이에 머물다) is the story of Korean American artists and their dreams, featuring new work by: Jung Ran Bae; Sohyung Choi; Kay Kang; Miran Lee; Young June Lew; Nicholas Oh; Younhee Paik; and Minji Sohn.

San Francisco artist Jennie Smith infuses her detailed drawings of the natural world with an imaginative sensibility.

Viewing hours are generally Monday through Friday, 9 am to 4 pm. The exhibit is located in a space also used for events and meetings; please call (510) 643-9670 or email in advance to confirm room availability.

This exhibition is dedicated to the centenary of the Russian Revolution that took place in October of 1917. The exhibition will take place in the Moffitt Library, and it will highlight several print-items from the revolutionary times.

Attendance restrictions: Access to the Moffitt Undergraduate Library is restricted and you'll need the UC Berkeley/ Cal Card for entry.

Marking a 50th anniversary, Bancrofts rare and unique collections documenting the 1967 Summer of Love are on exhibit in the corridor cases. Presented are images from the Bay Area alternative press, psychedelic rock posters and mailers, documentary photographs of the Haight-Ashbury scene and major rock concerts, and material from the personal papers of author Joan Didion and poet Michael...

¡Viva la Fiesta! explores the cycle of traditional religious and
patriotic celebrations that have for centuries marked the
Mexican calendar. The exhibition draws on unique historical
representations of the fiestas and examines their relationship
to communal identities, national politics, religious practices,
and indigenous customs. These original materials, which are
preserved in the... More >
